Thanks to an Angel Di Maria double and strikes from Julian Draxler and Edinson Cavani, Barca now stare Champions League elimination square in the face - to not even reach the quarter-finals is ridiculous to even contemplate.

Liverpool 3-3 Milan (aet) Liverpool won 3-2 on pens

Liverpool lifted the trophy in incredible circumstances in the 2005 final

Season: 2004-05

Stage: Final

GOING up against Paolo Maldini, Gennaro Gattuso, Andrea Pirlo, Kaka and Hernan Crespo, Liverpool were not expected to win the 2005 Champions League final.

After requiring a last-gasp Steven Gerrard wonder-goal to progress from their group, the Reds had battled their way to the final showdown in Istanbul, but lining up with Djimi Traore and injury-plagued Harry Kewell, they were sorely outgunned by the Serie A giants.

A minute in and the Reds were trailing... By half time they were 3-0 down and well out of the game as Milan toyed with the Premier League side.

A rousing rendition of You'll Never Walk Alone seemingly inspired Liverpool after the break as Rafa Benitez's decision to replace Steve Finnan with Dietmar Hamann paid dividends with Liverpool netting three times in just five minutes to leave the Italians shell-shocked at 3-3

Some famous Jerzy Dudek and Jamie Carragher heroics in defence in the half an hour of extra-time set-up the penalty shootout, famously won by the Reds as the side won their fifth 'Big Ears'.

The Miracle of Istanbul to this day goes down as one of the most exhilarating football matches in history.

Porto 3-2 Manchester United (agg)

ROY KEANE saw red as Jose Mourinho's Porto grabbed a 2-1 win over United at home.

However, in the second leg, Paul Scholes seemed to have won the tie as his goal put United ahead on away goals.

In stoppage time, Tim Howard could only parry a routine free-kick from the boot of Benni McCarthy into the path of Costinha to net the equaliser... and tie-winner.

The match is now famous for the Special One's celebration as he raced up the touchline, with captain Jorge Costa remembering: "When Costinha scored, I was going crazy. Mourinho was going crazy. Everybody was going crazy."
